Abstract: A call processing method comprises: a network device receives a call request message sent by an originating UE, determines, according to the call request message, that the originating UE supports a resource reservation procedure, and further transmits, to a media server, indication information indicating that use of the resource reservation procedure for negotiation about first media is not supported and use of the resource reservation procedure for negotiation about second media is supported, so that negotiation about the second media is implemented by using the resource reservation procedure.

Abstract: A method, an apparatus, and a system for accessing service by a Mobile Station (MS) are provided by the present disclosure. The method comprises the following steps: Gateway General Packet Radio Service (GPRS) Support Node (GGSN) or a next level gateway of the GGSN receives a service request carrying Virtual Access Point Name (VAPN) or a service request not including APN transmitted from a MS, performs a Deep Packet Inspection (DPI) processing to the service request, and identifies the type of the service; GGSN or the gateway sends the service request to the external data network corresponding to the service type. Therefore, accessing various types of mobile data services can be achieved through the service identification function of GGSN or GGSN gateway without modifying MS APN configuration by the mobile MS, therefore the service experiences for a MS user is enhanced effectively.

Abstract translation: 本公开提供了一种用于由移动台（MS）接入服务的方法，装置和系统。 该方法包括以下步骤：GGSN的网关通用分组无线业务（GPRS）支持节点（GGSN）或下一级网关接收携带虚拟接入点名称（VAPN）的服务请求或不包括从 MS对服务请求执行深度包检测（DPI）处理，并识别服务的类型; GGSN或网关将服务请求发送到与服务类型对应的外部数据网络。 因此，通过GGSN或GGSN网关的服务识别功能可以实现各种类型的移动数据业务的访问，而无需修改移动MS的MS APN配置，从而有效提高了MS用户的业务体验。

Abstract: A video media playing method includes: A media server receives a call request message from originating UE, where the call request message includes first session description protocol (SDP) information of the originating UE; the media server receives a first response message returned by terminating user equipment (UE); the media server determines, based on the first response message, that the terminating UE does not support a resource reservation mechanism/procedure; the media server sends a second response message to the originating UE, where the second response message includes second SDP information used to respond to the first SDP information; and the media server performs video media negotiation with the originating UE through the resource reservation mechanism/procedure.
